Berg Winds, Heat Islands and Urban Air

QUEST GEO-BERG-HEAT

Hot air in the wrong season

A winter day on the KwaZulu-Natal or Eastern Cape coast turns unexpectedly hot and dry. The humidity drops, the wind comes off the land instead of the sea, and the fire danger rating climbs. That is a berg wind. 🔥

Then there is the other side of it: a city that stays warmer than the farmland around it, and a valley that holds its own exhaust fumes on a still morning. All three are the same physics seen in different places.
